Design Rationale

The design decisions for this Content Quality Score Calculator prioritize user experience, scalability, and maintainability. React was chosen for the frontend due to its component-based architecture, which allows for reusable UI elements and efficient rendering. Node.js and Express provide a robust backend that can handle concurrent requests efficiently.

PostgreSQL was selected as the primary database for its reliability and support for complex queries, which will be necessary for analyzing and storing content data. Redis is incorporated for caching frequently accessed data and managing user sessions, improving overall application performance.

The modular file structure separates concerns and promotes code reusability. The implementation plan follows an agile approach, focusing on delivering core functionality early and iterating based on user feedback. The deployment strategy emphasizes scalability and reliability, using containerization and cloud services to ensure the application can handle growing user demands.

Security is a top priority, with JWT authentication and bcrypt password hashing protecting user data. The CI/CD pipeline and monitoring tools are included to facilitate rapid, reliable updates and proactive issue resolution.

Overall, this architecture provides a solid foundation for building a performant, secure, and user-friendly Content Quality Score Calculator with room for future expansion and feature additions.
